jQuery Grid Plugin - jqGrid

I've trying to put together my first jqGrid for ASP.NET MVC3 via this tutorial:

http://haacked.com/archi...d-w.....aspx 

The Controller looks like this:

public ActionResult jqGridTest(string sidx, string sord, int? page, int? rows)
{
var jsonData = new
{
total = 1, // we'll implement later 
page = page,
records = 3, // implement later 
rows = new[]{
new {id = 1, cell = new[] {"1", "-7", "Is this a good question?"}},
new {id = 2, cell = new[] {"2", "15", "Is this a blatant ripoff?"}},
new {id = 3, cell = new[] {"3", "23", "Why is the sky blue?"}}
}
};
return Json(jsonData, JsonRequestBehavior.AllowGet);
}

The View is called jqGridTest.cshtml and looks like this:

@{
ViewBag.Title = "jqGridTest";
}
<link href="../../Content/ui.jqgrid.css" rel="stylesheet" type="text/css" />
<script src="../../Scripts/jquery-1.4.4.js" type="text/javascript"></script>
<script src="../../Scripts/jquery.jqGrid.min.js" type="text/javascript"></script>
<script src="../../Scripts/js/jqDnR.js" type="text/javascript"></script>
<script src="../../Scripts/js/jqModal.js" type="text/javascript"></script>

<script type="text/javascript">
jQuery(document).ready(function () {
jQuery("#list").jqGrid({
url: '/Home/jqGridTest/',
datatype: 'json',
mtype: 'GET',
colNames: ['Id', 'Votes', 'Title'],
colModel: [
{ name: 'Id', index: 'Id', width: 40, align: 'left' },
{ name: 'Votes', index: 'Votes', width: 40, align: 'left' },
{ name: 'Title', index: 'Title', width: 200, align: 'left'}],
pager: jQuery('#pager'),
rowNum: 10,
rowList: [5, 10, 20, 50],
sortname: 'Id',
sortorder: "desc",
viewrecords: true,
imgpath: '/scripts/themes/coffee/images',
caption: 'My first grid'
});
}); 
</script>

<h2>jqGridTest</h2>
<table id="list" class="scroll" cellpadding="0" cellspacing="0"></table>
<div id="pager" class="scroll" style="text-align:center;"></div>

However, when the page renders all that is displayed is this:

{"total":1,"page":null,"records":3,"rows":[{"id":1,"cell":["1","-7","Is this a good 
question?"]},{"id":2,"cell":["2","15","Is this a blatant ripoff?"]},{"id":3,"cell":["3","23","Why is the sky blue?"]}]}

Being new to this technology, I'm not too sure what I'm doing wrong.

Thanks.
